Hyper-V Replica Kerberos Error

David is one of our Premier Field Engineers and he approached us with an interesting problem where the customer was encountering a Kerberos error when trying to create a replication relationship. On first glance, the setup looked very straight forward and all our standard debugging steps did not reveal anything suspicious.

The error which was being encountered was “Hyper-V failed to authenticate using Kerberos authentication” and “The connection with the server was terminated abnormally (0x00002EFE)”.

Hunted for days to find a solution to this error. Turned out to be a misspelt SPN. Also , it may be worth trying to replicate a 'test VM' from DR to Prod ( this worked for me and made me double-check the SPN's on the DR side )
